In contrast to wellbore phenomena, which rarely affect the long-term performance of a well, near-wellbore phenomena almost always affect a well’s long-term performance. Each of the phenomena discussed in this chapter causes a transient pressure response at early times. This transient period is frequently obscured by wellbore storage, allowing the pressure response to be modeled as a constant skin factor. However, under certain conditions, the transient response may be visible during the transition from wellbore storage to infinite-acting radial flow.
Section 10.2 gives a brief review of the finite-thickness skin factor model originally proposed by Hawkins (1956) .
Sections 10.3 through 10.5 introduce the concept of geometric skin factor and present geometric skin factor models for three common types of completion, cased-hole/perforated completion ( Section 10.3 ), partial penetration/ limited entry completion ( Section 10.4 ), and deviated well completion ( Section 10.5 ).
